Yep, I think you're about right there Geo. Maybe move the front edge of the forward white stripe 1mm or so forward ?
The roundels are slightly higher than 'standard', emphasised by the lack of the wing root fillet in the pic of the real aircraft. From memory, one of the factories, I think CBAF, painted the roundels in a slightly different place to all the other constructors, with the leading edge of the roundel taking it's line from a different frame number.
